VCSC Presence works with MOVI 4.2, but not 4.3. But it works with the VCSE

I have run into an issue with a VCSC. For some reason, Presence information doesnt seem to reach any MOVI client registered to the VCSC. The odd part of it is it is just specific to Jabber client 4.3 and greater. When I register the same client to the VCSE, it registers fine.

Has anyone else ran into this? I just blew away the majority of the config and rebuilt it, but the issue still remains.

Aside from just the presence information, all other calling works on the VCSC.

There is some account thing that is not allowing me to work with Cisco TAC to resolve the issue (Equipment was purchased through OnX, while my company, igniteCSG (we are a Cisco partner, as well) provides services and support).

So, I am taking it up with Cisco services to figure out how this can be done.
